LASTING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 635,129, dated October17', 1899.

Application filed April 15, 1898. Serial No. 677,652. (No model.)

EATON, of c c are pivoted upon the ends of arocking Boston, in the county of Suffolk and State of bar cl of rigidconstruction, pivoted upon a Massachusettahaveinvented certain new andstud or fulcrum d, projecting forward from useful Improvements inLasting-Machines, of the shelf b at the front end of the bed-plate.

which the following is a specification. Thus far the constructiondescribed is no This invention relates to machines for lastdifferentfrom that illustrated and described ing over the heel and toe portionsof boot and in the patent to Fred P.

The toe-clamp consists of a ary racks e andimpart an accelerated forstrip 0 of leather or suitable flexiblematerial, ward movement to the racks 6 6 this motion backed by rigidcurved-arm or yoke sections being imparted to the wipers by the linksc cc, which are pivotally connected together the wipers being thus causedto move forward 45 at c and are provided with ears 0 0 conwith thecarrier and to swing inward toward 5 nected to bell-crank levers c 0'The ends each other, the segmental ribs moving in the of the bellcranklevers are connected by segmental slots of the carrier constituting thecurved links 0 c with the inner ends of the pivotal connections betweenthe carrier and arms a, the links crossing each other, so as the wipers.50 to constitute equalizing connectionsbetween The described forward andinward move- Ioo ment of the wipers causes them to properly wipe theupper over upon the bottom of the last, the toe portion being wipedbackwardly or lengthwise of the last, while the said side portions arewiped forwardly or crosswise of the last.

In order to adjust the wipers toward or from each other, a screw-bar h,journaled in a bearing h on the bedb and having a handwheel 77. has itsend passed into the nut 0 so that by turning the screw-bar in onedirection or the other the wipers may be caused to approach or recedefrom each other about a common center.

As has been previously stated,the toe-clamp is mounted upon a rockingbar, so that it is automatically adjustable by the engagement of alasttherewith to fit a right or left last that is to say, the rockingbar may be swung upon its pivot, whereby when the median line of the toepart of a last is at an inclination to the median line of the machinethe toeclamp will automatically swing to correspond thereto.

I connect the wipers with the toe-clamp, so that when the last andtoe-clamp are brought into contact and the latter is automaticallyadjusted to fit the last the wipers are likewise automatically adjustedbefore the last comes into contact therewith. The connecting meansconsist of a bell-crank lever z', pivoted on the under side of thebed-plateb and connected by a link with the rocking bar. The other endof the bell-crank lever is provided with a stud t fitting in a slot inthe end of a vibrating bar 9', pivoted at j to the said under side ofthe bed. The rear end of this vibrating bar is provided with a stud g,projecting into'a slot in the wedge g.

Now it will be seen that when the rocking bar is rocked about its centerof motion the link 7 swings the bell-crank lever around its stud, andthis in turn swings the lever j about its pivot-stud and thrusts thewedge to one side or the other, this depending upon whether the tiltingbar at the front of the machine has been moved to correspond with aright or a left last. Hence the wipers, which are adjustable about acenter of motion, are adjusted automatically in the same direction bythe last before the latter comes in contact with them. The wiper and theadjusting mechanism is comparatively light, and little resistance has tobe overcome when a shoe is brought into contact with the toe-clamp andthey are adjusted in accordance with its shape.

The invention has been described as adapted for use in connection withtoe-wipers; but it will be understood that it can be equally applied toheel-wipers.

Having thus explained the nature of the in- Vention and described a wayof constructing and using the same, though without attempting to setforth all of the forms in which it may be made or all of the modes ofits use, I declare that what I claim is- 1. A lasting-machine comprisingwipers movable toward or from each other about a common center, acarrier having pinions, sliding racks intermeshing with said pinions,and connected to said wipers, adjustable racks intermeshing with saidpinions, and mechanism for moving the last said racks relatively to eachother, for the purpose of adjusting the wipers in the same directionabout the said common center.

2. A lastingmachine comprising wipers movable toward or from each otherabout a common center, a carrier having pinions, sliding racksintermeshing with said pinions, and connected to said wipers, adjustableracks intermeshing with said pinions, and a bar for adjusting one of thelast said racks relatively to the other.

3. A lasting-machine comprising wipers movable toward or from each otherabout a common center, a carrier having pinions,

sliding racks intermeshing with said pinions,

and connected to said wipers, adjustable racks intermeshing with saidpinions, and a wedge for adjusting one of the last said racks relativelyto the other.

4. A lasting-machine comprising a nonrotary head, wipers movable about acommon center, slides connected to said wipers,means including alongitudinally-movable wedge for adjusting said slides relatively toeach other to swing the wipers in the same direction about the said'center, and mechanism movable independently of said adjusting means foroperating said wipers to approach and recede from each other.

5. A lasting machine comprising wipers movable about a common center,two pairs of opposing racks, one rack of each pair being connected toone of said wipers, mechanism for adjusting the other racks of saidpairs relatively to each other, and a carrier provided with pinionsintermeshing with the opposing racks of the said pairs.

6. A lasting-machine comprising wipers movable about a common center, asliding block, slides interposed between said block and said wipers, andmechanism including coacting gearing interposed between the ends of saidslides and said block for adjusting one of said slides relatively to theother, said parts being constructed and arranged whereby when the saidblock is moved the wipers are moved toward or from each other, and whenthe said mechanism is operated, the said wipers are swung in the samedirection about the said common center.

7. A lasting-machine comprising wipers movable about a common center,adjustable slides connected to said wipers, a sliding block foradjusting said slides simultaneously in the same direction to move saidwipers about their said common center, and mechanism interposed betweensaid slides and said block for adjusting said slides in oppositedirections.

8. A lasting-machine comprising wipers movable about a common center,adjustable slides connected to said wipers, a sliding block foradjusting said'slides simultaneously in the same direction to move saidwipers about their said common center, mechanism interposed between saidslides and said block for adjusting said slides in opposite directions,a movable clamp for the end of the shoe,'and connections between saidclamp and said mechanism.

9. A lastingmachine comprising wipers movable toward or from each otherabout a common center, acarrierhavingpinions, sliding racks intermeshingwith said pinions, and connected to said wipers, adjustable racksintel-meshing with said pinions, mechanism for moving the last saidracks relatively to each other, for the purpose of adjusting the Wipersin the same direction about the said common center, a swinging clamp forthe end of the ARTHUR W.
